Running every night through October 31st, Washington Walks is hosting spooktacular tours of the haunted pasts surrounding Lafayette Park. Hear tales about the eerie navy hero Stephen Decatur, the foreboding pasts of Henry Adams and his troubled wife Clover, and relive the night of April 14, 1865 when the grim reaper stalked Abraham Lincoln. The tour ends at the most haunted home in the city, the Octagon Museum. That is…if you make it through the entire tour…MUHAHAHAHAHAHAHA! Cue Vincent Price.
